Migrating Teams Calling Bot (EchoBot) from VMSS to Windows Containers / ACI?
Hi everyone, I have built a Microsoft Teams Calling Bot using Application-Hosted Media based on the official C# EchoBot sample: https://github.com/microsoftgraph/microsoft-graph-comms-samples/tree/master/Samples/PublicSamples/EchoBot Currently, our signaling logic is fully serverless and runs efficiently on Azure Functions. However, the actual media processing (using the C# Calling SDK which relies on native Windows media binaries) is deployed on VMSS with Windows Server, just like the repository's default deployment guide suggests. Running these Windows VMs continuously is becoming extremely expensive, and we are looking for a cheaper, modern, or "on-demand" alternative to handle the media pipeline. Since raw audio processing strictly requires these native Windows-based Media binaries, I would like to ask the community: 1. Windows Containers (ACI / AKS): Has anyone successfully run this C# EchoBot/Media SDK inside Windows Containers (such as Azure Container Instances or AKS)? If so, how do you handle the public IP and port-binding requirements for the media sockets (since the platform needs direct public connectivity for UDP/TCP traffic)? 2. On-Demand Provisioning: Are there any known architectures or best practices for spinning up the media processor only when a call starts (e.g., triggering an ACI instance via the Azure Function signaling bot) and tearing it down afterwards to keep costs near zero when idle? 3. Alternative Approaches: If you have solved this high-infrastructure cost problem for a real-time raw audio bot in production, what architecture did you end up using? Any documentation, GitHub references, or architectural advice would be highly appreciated! Thanks!
❓ Can't remove member from Microsoft Teams Group Chat using Graph API with Application Permission
Hi everyone, I’m currently working on creating a Teams group chat using Microsoft Graph API with application permissions, and I’ve run into several issues that I hope someone here can help clarify. Creating group chat with members and installed app (works) I followed the documentation here: “Create a one-on-one chat with installed apps” ➜ https://learn.microsoft.com/en-us/graph/api/chat-post?view=graph-rest-1.0&tabs=http#example-3-create-a-one-on-one-chat-with-installed-apps Using application permissions, I successfully: - Created a group chat - Added multiple members - Installed my Teams app into the chat automatically My application has already been granted the following permissions: ChatMember.ReadWrite.All ChatMember.ReadWrite.WhereInstalled The purpose is to allow the app to add or remove chat members without requiring a signed-in user, since I am using fully non-delegated application permissions. However, when I try to remove a member from the group chat using Graph API with the application token, the request fails and returns an error. Trying RSC-granted approach – app not installed Next, I tried creating a group chat using the RSC-granted app approach: https://learn.microsoft.com/en-us/graph/api/chat-post?view=graph-rest-1.0&tabs=http#example-4-create-a-one-on-one-chat-with-rsc-granted-apps With the following permission: - ChatMember.ReadWrite.All And permission type: application The group chat is created successfully, but the app is not installed inside the chat, which means I still can’t proceed with removing a member using the app context. So this solution also stops midway. Creating chat first, then installing the app (also fails) Lastly, I attempted another method: Create the group chat normally After creation, install the app into it using this endpoint: https://learn.microsoft.com/en-us/graph/api/chat-post-installedapps?view=graph-rest-1.0&tabs=http I used an application access token again, but the request returns the same error as case #1 when attempting to remove a member.
How to Implement OAuth for a Bot-Based Message Extension App in Microsoft Teams for Graph API?
I have created a bot-based message extension app using the Teams Toolkit and need to call the Microsoft Graph API, which requires OAuth implementation. So far, I have created the app in the Teams Developer Portal, registered the app in Azure App registration, and registered the bot in the Bot Framework Developer Portal (dev.botframework.com). However, I am unclear about the OAuth flow and the specific configurations required. Can someone provide a detailed guide on how the OAuth flow works for a bot-based message extension in Microsoft Teams, the specific configurations needed in the Azure app registration, how to configure permissions and consent for accessing the Microsoft Graph API, and any additional settings required in the Teams Developer Portal or Bot Framework Developer Portal? Any guidance, code examples, or references to detailed documentation would be highly beneficial.
Listing tabs in a channel encounters "Value cannot be null. (Parameter 'stringToUnescape')" error
Hi, We use the https://learn.microsoft.com/en-us/graph/api/channel-list-tabs?view=graph-rest-1.0&tabs=http in our product, and it works fine for all cases, except one. We notice that when sending this API with one of our customer's channel, we will get the following response: { "error": { "code": "BadRequest", "message": "Value cannot be null. (Parameter 'stringToUnescape')", "innerError": { "code": "InvalidRequest", "message": "Value cannot be null. (Parameter 'stringToUnescape')", "details": [], "date": "2024-05-10T01:38:38", "request-id": "10e6b074-a2dc-4950-aae5-8bbe68d838b8", "client-request-id": "10e6b074-a2dc-4950-aae5-8bbe68d838b8" } } } No matter we tried how many times, this error persists. For comparison, if we send the same API on another channel, we can get correct response. Do anyone also encounter this error? We hope Microsoft could help us figure out why and how we can handle this case. Thank you.
Just as we created an onlineMeeting in an application using the Graph API, is it possible to create
Hi, I confirmed the announcement that Teams Live Events would be discontinued in September last year. In addition, it was confirmed in the roadmap that Town Hall Graph APIs will be rolled out in May 24. It was possible to grant permission for applications to create Live Events. (Currently changed to Not supported after the announcement in September last year.) Is it possible to grant creation permission to an application for Teams Town Hall? If this is not possible, I must prepare to change the structure of the application I have created. I don't see any mention of this anywhere, so I'm asking here.
Number of participants is reported inaccurately on CallRecord endpoint
We have been pulling CallRecord data via Graph API for analysis. One particular record grabbed our attention. According to the JSON return from Graph API there were 40 participants and 60 sessions. However, the online CQD dashboards showed over 120 participants for the call. So we started to troubleshoot and noticed that our logic does not support the session "nextLink" and there were more than 60 sessions for this group call. We fixed it; so now we can support the pagination. However, the "participants" array field in the JSON return still shows 40 participants. We checked all the returns from Graph API. Only the first return that we made against the call-id has the participants section; the rest of the paginated returns for session does not even have a participants section. They only include the session and segment info. I think subsequent returns do not even have the stream metric details either. So is this a expected behavior? Do we need to call the link in nextLink section differently, so that the return includes all the participant data? Thanks
Access Teams Attendance using RSC permission
Objective When a teams video call finishes, get a list of users who attended the meeting. (ideally with the joined and left times) Approach In a teams app manifest file you can add Resource-specific consent (RSC) Application Permissions: ChannelMeetingParticipant.Read.Group Read the participants of this team's channel meetings. - Allows the app to read participant information, including name, role, id, joined and left times, of channel meetings associated with this team, without a signed-in user. OnlineMeetingParticipant.Read.Chat Read the participants of the meetings associated with this chat. - Allows the app to read participant information, including name, role, id, joined and left times, of meetings associated with this chat, without a signed-in user. Using a teams app with the ChannelMeeting.ReadBasic.Group and OnlineMeeting.ReadBasic.Chat permission I get a notification when a meeting ends. Using: var meetingInfo = await TeamsInfo.GetMeetingInfoAsync(turnContext); I can get the: meetingInfo.Details.MsGraphResourceId which gives me a value that looks like: MSpjY2VhZjE3My04MjBk...Truncated...ZWFkLnYy Questions/Help Needed How do I make use of the RSC permissions granted in the Teams App manifest to now request the participants who attended the meeting? What API call do I need to make? The documentation for this seems lacking? The RSC permission for getting meeting participants is referred to here: https://learn.microsoft.com/en-us/microsoftteams/platform/graph-api/rsc/resource-specific-consent but I am unable to find out how I can make use of this permission to make graph calls? Other comments and posts refer to getting Online Meeting Artifacts (Giving access to recordings, transcripts and attendance report) however this requires the Teams Admin to grant the very broad permission to OnlineMeetingArtifact.Read.All whereas I believe I should be able to do this via permissions granted via RSC which would be granted on a per channel or meeting basis when a user adds the app rather than having access to all meetings. - Also I only want access to the attendees and avoid asking for permissions that give access to meeting recordings which could contain sensitive information. Can you please advise or direct me to where I can find help on how to make use of the ChannelMeetingParticipant.Read.Group and OnlineMeetingParticipant.Read.Chat permission to access the meeting attendees. Many thanks, Daniel MitchellTeams onlinemeeting recording file creating and saving error
